Be it known that 1, CHARLES (3. Hansnn, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania haveinvented certain new and useful improvements in the Apparatus for-Channeling Rock, of which the following is a specification.

.This invention relates to apfiaratus for channeling. rock, more especi y for use in quarries for cutting blocks credimension stones and for use wherever it is desired to cut channels in the rock such as canal work,

building foundations and work of similar. character. p

Channeling has heretofore been a continuous operation, by running the channelmachine forward and back over the blows of the channeling machine through the steels upon the rock. The process is necessaril slow and requires substantially great skil of theoperator. Furthermore the heavy blows delivered on the steels by the channeling machine often bruises or fractures the stones for a considerable dis- -tance from the cut and this bruised or fractured material is, useless so that the blocks must be planed entailing considerable waste.

'lheprima'ry objects of the present invention are to simpli the methods-andaparatus for channelmg enable the mac 1 to be operated and the channel cut by an operator not possessing any special slm'll and avoid bruising and fracturing the stones.

-- Instead ofcutting a continuous channel as heretofore, m invention consists in first simultaneously rilling a series of equidistantly relatively widely spaced holes bymeans of drilling machines along theline ofthe desired channel, then simultaneously drilling another series of holes on the same line close tothe holes in the first series, and continumg to progressively drill series of holes'in the same manner on the line of y the channel until the spaces between the between the, holes to channel. I The broaching operation is sub- .55 1" holes in the first series are filled with substantially equidistantly relatively closel' spaced holes.

eration, with broaching bits substituted for.

drilling bits in the drllling machines.

For carrying outthis cycle of operations, the apparatus may conveniently consist of a traveling carriage having an upright frame with a plurality of rock drills prefa channel.

In accordance with my invention faster at less cost than heretofore. The conditions of the quarry will have less effect on thissystem as the track work will not have to be so carefull adjusted as with the old method, and t e stone will be less bruised than is the case where a continuous-slot is channeled, because with my method and machine t e drill steels are struck much channeling may be efi'ected and consequently lighter blows with larger penetration of Suitable apparatus for carrying out the operations are illustrated in the accompanying drawings, in ,vvhich igure 1 is a side elevationof a traveling carriage and rock drills mounted thereon for carrying out the herein described inventio'n j Figure 2 is an end elevatidn of the same,

.first simultaneously drilled at equal disward again and the holes 3 indicated in Figure that the same method tances apart along the line of the channel. The distance between the holes 1 corresponds to the distance between the rock drills on the carriage, regardless of the number of drills. In. this instance the cycle of operations is shown carried out with four rock drills shown in F i re 1, but it is to be understood that any esired number may be used, and the capacity of an operator should be ten or more of these machines on a frame.

After the first holes 1 have been drilled, 1

as shown in Figure 6, the drilling machine carriage is moved forward along the line of the cut the desired distance, and the series of holes 2 are simultaneously drilled, as shown in Figure 7,'preferably close'to the holes 1." The carriage is then moved forare drilled, as shown in Figure 8. Lastly the holes 4 are drilled which completes the line of holes taken as an illustration of the method, as 9, it being understood would be carried out with any desired number of drills.

In order to complete the cut, the drill steels are replaced by broaches B as shown in Figure 10 and the rock walls between the holes are broached to form the channel indicated in Figure 11. The broaching is carried out progressively in substantlally the same manner as the drilling, that is, four broaches are simultaneously operated, or as many as there are mach es on the travelin carriage. V

Suita le apparatus for carrying out this cycle-of operations is illustrated in Figures 1 to 5 inclusive showing one preferred form, also it is to be understood that other forms of apparatus may be devised for carrying out the cycle of'operations and I am not to I be'understood as limiting the inventionto the apparatus shown.

The carriage C travels on the track D and is provided with the upright frame-E preferably having vertical guide rods F on which the clamps G slide independently of each other. Rock drills, preferably of the hammer type H, are suitably mounted in the clamps or mountin G, in this instance the handles J being eld upon clamping driven by a suitable motor U so that the he lifted to the top drilling machines may ,the weight of the of the frame for startin machine and mounting heavy to hold the drill steel to its work. The rock'drills are provided, as shown in Figure 1, with the usual drill steels V for drilling the series of holes and eachrock' drill is fed to theothers. Suitable controlling means are provided for controlling the winding drums S, in this instance each drum being provided Wlth a clutch member a cooperatin with a clutch member I) rotatable therewit but longitudinally slidable on the driving shaft T as by means of the lever c. Eachaclutch memier 72 is providedwith a brake 0! connected to toggle levers e operatiwely connected to be controlled by the controlling lovers 0 so :that when the lever c is moved toward its drum S in the position.indicated in full lines in Figure 4, the brake d is released, the clutch is thrown into operative position and the drum S will wind up the rope Q to lift its work independently of all trolling lever c is moved into"v position as indicated in dotted lines in Figure .l: with the detent f in the notch g in the quadrant it the clutch will be released andthe brake will be thrown on to hold the drilling machine in raised position. The controlling lever c is in neutral position with the brake and clutch released when the detent f is in the notch j in which position the rockdrilling machines are in operation and feed downward to their work. All the levers c are located at the front of "the frame where they are easily accessible and each of the winding dr ms is adapted to be controlled independently of the others. An suitable hose line connection is is provided lying motive fluid as compressed air uner pressure to the rock drills. The lower frame is preferably being sufiicientlyfor sup-.

winding drums S on in Y I %)ne end of the carriage as shown, is provided with a bracket 11 suitably secured thereto and having a horizontal plate q provided with a plurality of separate-spaced a ertures 1', through one of which a spacing -p ug .8 is ada ted to be inserted for spacing the series of oles. In Figure 1 the spacing plug sis shown in the hole A reviously drilled in the rock, for th e proper spacing for the first series of holes 1 for the 1 the cycle of operations. By means of the spacing bracket 11 and the plurality of holes 7* in the plate 9, any desired spacing betweenthe series of holes in the rock may be provided. The spacing device is convemently located at the front of the frame in proximity to the controlling levers c, clamps o and hose line connection is. This arrangementtends to simplify and improve the operation of the device. It is to be understood that the broaching operation indicated in Figure 10 may be carried out after a given series of holes in the rock have been drilled, or the broaching operation may await the completion of a long series of drilled holes, several hundred feet long, or

5; as long as desired.
